The PM240-2 and PM250 Power Modules are already designed for Safety Integrated.西门子中国代理商-PLC模块代理商

In conjunction with a standard Control Unit, the drive provides the safety function STO.
The PM240-2 Power Modules, frame sizes FSD to FSG additionally offer STO acc. to IEC 61508 SIL 3 and EN ISO 13489-1 PL e and Category 3.

In conjunction with a fail-safe Control Unit, the drive can be turned into a Safety Integrated Drive with comprehensive safety functions.

The Safety Integrated functions are completely integrated into the drive system. They can be activated via fail-safe digital inputs or via PROFINET or PROFIBUS with PROFIsafe.西门子中国代理商-PLC模块代理商

The Safety Integrated functions are implemented electronically and therefore offer short response times in comparison to solutions with externally implemented monitoring functions.

Safety Integrated encoderless

The safety functions do not require a motor encoder; the implementation effort is minimal. Existing machines in particular can be updated with integrated safety technology without the need to change the motor or mechanical system.

The STO function can be used without any restrictions for all applications.

The SS1, SLS, SSM and SDI functions are only permissible for applications where the load can never cause acceleration. An encoder that is used for the purposes of motor control has no significance for the safety functions here.

Safety Integrated overview

The availability of Safety Integrated functions depends on the type of Control Unit. Standard Control Units and fail-safe Control Units are available.

The CU240E-2 standard Control Units have STO and the CU250S-2 Control Units have STO, SBC, and SS1 as standard.

The fail-safe Control Units offer Extended Functions (SLS, SDI, SSM) in addition to the Basic Functions (STO, SS1). The Basic Function SBC is currently supported by the CU250S-2.

A license is required for operation of the Extended Functions on the CU250S-2 Control Unit. It is of no consequence here which Safety Integrated functions are used and how many.

The license can be ordered as an option with the memory card. Alternatively, a single-user license can also be purchased.

Safe Brake Relay西门子中国代理商-PLC模块代理商

The Safe Brake Control (SBC) function requires a Safe Brake Relay. The Safe Brake Relay allows safe control of electro-mechanical motor brakes.

The 24 V DC solenoid of the motor brake is directly connected to the Safe Brake Relay. External surge suppressors are not required. The cable harnesses for connection to the Power Module are included in the scope of supply.西门子中国代理商-PLC模块代理商

With the Safe Brake Relay function, the brake is controlled in accordance with IEC 61508 SIL 2 and EN ISO 13849-1 PL d and Category 3.
